Case Study: 3 – Scenario 3 (QUESTION 24 – QUESTION 34)BackgroundYou are developing a Windows Store news aggregator app that will retrieve data from RSS feeds and social networks based on the user’s subscriptions.Application StructureThe app will run locally on the user’s device. User preferences will be available locally. When a user starts the app, the app will load the RSS feed and social network information. The app will retrieve data from RSS feeds by using the FeedRetriever class. The app will authenticate to and retrieve data from social networks by using the SocialRetriever class. By default, data is presented in a ListView control. Relevant portions of the app files are shown. (Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.)Technical BackgroundThe design team has provided a custom XAML code segment for the itemTemplate attribute of the GridView control that displays RSS feeds. The custom item template is named newTem plate. It will not be used in other GridView controls.RequirementsBusiness RequirementsThe app must enable users to perform the following tasks:– Define a feed title.– Define a list of RSS feeds that the users want to subscribe to.– View information about topics that are popular on the users’ selected social networks.– Share content that is aggregated by the app.– Search aggregated content by using only the Search charm.– Share RSS feed content by using the Share charm.– Display general help information by using the Settings charm. The app must list the name of each social network to which the user subscribes. The app must indicate whether the user is authenticated to that social networking site.The available data sources will be expanded to include JSON data from a third-party social networking site that is hosted by Litware, Inc. An SSL connection to the Litware social network is available.Technical RequirementsThe app has the following technical requirements:– Retrieve user data from the social network services by using the authentication credentials.– When making an HTTP request for content, read all content prior to acting on the response.– When SSL is available, use SSL to retrieve data from social network providers.The code that is used to retrieve data from RSS feeds must be reusable. The app must display the information about the user’s social network subscriptions in a layout control. The app must display authentication screens from the social networking sites when an authentication screen is available. The custom XAML code that was provided by the design team must be available for all ListView controls in the app. Data from the FeedRetriever class must be presented in a data control. Two developers will create the SocialRetriever class, with the following assignments:– Developerl must update methods for getting data.– Developed must implement three new methods for exposing data to the user interface.– All methods must be self-contained and must not affect other methods in the SocialRetriever class.– Multiple developers must not work in the same file at the same time.
